An “Active” smoke (and gas) detection system constantly draws in and samples the air in a space. These systems detect fire or toxic gasses much earlier than traditional “Passive” smoke detection which waits for the smoke to reach a detector. These precious minutes can make a huge difference when protecting spaces that contain business critical equipment or valuable assets, such as server rooms, control rooms, museums, etc.
VESDA (Very Early Smoke Detection Apparatus) is the market leader when it comes to “Active” detection systems. Early warning thresholds can be set to provide early notification of possible fire or toxic gas conditions. As additional thresholds are crossed, alarms can be configured to sound, the fire department can be notified, and pre-action sprinkler valves or gaseous fire suppression systems can be activated.

I agree with warne. it is more like being proactive and reactive rather than active or passive. nonetheless, great article.
This was a very informative article regarding fire detection systems. One of the pieces of information lacking is the price difference between active and passive detection. If not cost prohibitive, why would passive ever be the choice?
This blog is informative about the differences of active and passive smoke detection systems. What I like about active detection systems is that its early warning thresholds, so there is no need to wait for the smoke to reach a detector.
VESDA is not going to be forgotten in a hurry. Proactive smoke detection system is a more apt name
Such system should be a requirement to every establishment. Safety and precautions should be prioritize.
